[PD] Help needed for string manipulation in PD
Hello, Currently I am stuck at one point in my multichannel recording patch. The problem is that I want to dynamically read the list of wav-files from a specific folder using a text file. For this case, I am using the textfile object. One line of the text file reads like sp01_48kHz/swih7 Can there be a way of separating this line into separate strings like 'sp01' '48kHz' 'swih7' I need for instance the first string to create the name of wav-files to record the data. In addition to that is there any conditional statement (object) in PD, which I can use to only generate the wav-files, e.g., when sp01 changes to sp02 in the text file as I have 10 utterance for every speaker and I want to store them separately? I will really appreciate help in this regard Thanks, Tania ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
[PD] how to set paths in Pd running on windows xp?
Hello, I am having trouble setting paths to load some wav-files in Pd running on Windows XP, as for path setting backslash (\) is used instead of forwardslash (/).

Re: [PD] Recording question
Well now I am facing a problem, I guess I was too excited to really check whether this option worked properly or not! The problem is that I have a patch in Pd, where I am using adc~, writesf~ to write the streaming data into wave files. When I initialize Pd, it recognizes the aggregate device, I click on it and select the no. of channels to the total no. of inputs I have with the aggregate device, say 8. When I start the recording and finish it. Open the wav files in audacity, only two channels seems to be active the rest have nothing in them! Can someone, who has used this feature to do recording with Pd please let me know, what I am doing wrong!. thanks tania On Dec 19, 2007 2:00 AM, simon wise [EMAIL PROTECTED] wrote: On 19 Dec 2007, at 9:51 AM, Roman Haefeli wrote: hey, that is cool to know (as a non-osx user, i wouldn't have expected something like that to exist, but i think, i know quite some people who could benefit from that). just in case you know: do you have an idea how this system deals with the fact, that each of this cheapo soundcards have their own clock? does it use one as the master clock and does apply a samplingrate conversion to the other in order to sync it? i am asking, because i would like to know, if any decrease in sound quality is expected when you use aggregate. I've used it a couple of times to get some extra outputs from a laptop, and it has worked fine but I haven't used it extensively. There are options to choose which clock source is used, and options (for each physical device) to re-sample the audio so it seems that it will re-sample if you choose, or not if it works ok without - I guess that would depend on things like the abilities of the cards and their drivers. It has been around for a while - maybe introduced in OSX 10.3??? simon ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Recording question
yes I tried the test audio patch, all the input channels are active but it seems that only the first two are getting the input the rest have noise .

[PD] Recording question
Hi List, I have a question regarding a patch that I made for recording multi-channel audio. For the 16 channels, we are using Fireface 800 with an extension board. It works quite well! For a specific application, we are trying to use the two iMic's with a USB plug to record at least 4 channel audio. When I initialize PD and select the audio settings, it shows me two of these seperately in the option, the recording for one works but not for the other! The question is if I can use PD to record simultaneously from two different source from a single patch or somehow get the recording from both! regards, Tania ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
Re: [PD] Recording question
Hi Derek, I am working on Mac Pro osx 10.4, I have not tried the two different soundcards option, we use the multichannel sound card for our recordings. But we wanted to try the recording with iMic's, do you know a link or a way to link two or multiple iMics together? Thanks for the link, it looks interesting, I will check it out in detail but this is not the direction we want to proceed at the moment. tania On Dec 18, 2007 12:06 PM, Derek Holzer [EMAIL PROTECTED] wrote: Hi Tania, are you able to record from two different soundcards simultaneously in any other application on your computer? I ask because this isn't usually the case in my experience. Many have dreamed of linking several el cheapo soundcards to get an inexpensive multichannel soundcard from them. Two (or more) different soundcards have two different sample clocks and these won't be in sync, among the main problems. Google el cheapo soundcard, or check here: http://quicktoots.linuxaudio.org/toots/el-cheapo/ To see how this might be accomplished on Linux. There, it requires the hardware modification of removing the clock from one card and connecting it to the clock of one master card. And I quote: The challenge in recording with more than one soundcard at once in any computer under any operating system is to make the cards syncronize. The actual sample rate of each card is depending on the crystal used in the card. To cut the component cost of consumer grade soundcards cheap crystals, with wider tolerances than those used in pro equipment, are often used. As a result, when using two cards at once one can have a real sample rate of 44.099 kHz in one card and a samplerate of 44.101 kHz in the other. This is no problem when recording with one card only, but the difference in the sample rates will cause phase shifts in the recording when using two cards. Phase shifts make the high frequencies of the recording e.g. cymbals sound bad. Further, not all audio drivers can drive cards that are not in exact samplerate sync. Some pro-cards come equipped with a link to connect multiple cards to run in sync. Consumer cards do not have this feature. This Howto describes a simple hardware modification to create such a synchronisation link between consumer grade cards. Without hardware modifications it is very difficult to ensure the cards are in sync. You haven't mentioned the operating system you are running, BTW... Maybe other operating systems allow multiple (consumer) soundcard recording, I haven't tried. In PD, I don't think it's possible. If you had a way of getting your two IMics to be seen as one soundcard (the Linux el cheapo method), then you could try it. best, d. tania habib wrote: Hi List, I have a question regarding a patch that I made for recording multi-channel audio.

Re: [PD] Recording question
the OSX audio system does have a system to join two different soundcards -open Audio MIDI Setup (usually in the Utilities folder) -then open the Aggregate Devices Editor from the Audio menu - here you can create a new device, select which will be the master clock etc -this new device can then be selected and used in the usual manner Yes! I have tried it and it seems to work now, as Pd recognizes this aggregate device, I have to do a detailed recording session, to exactly see how well suited it will be for the application Thanks this option really seems to works well!! tania ___ PD-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
